Application filed July 9, 1907. Serial No. 332,888. l

To all 'u'liom it mfry concern.:

Bc it known that I, 'liioMAs Puiivis, a citizen of the United States,residing at INorth Birmingham, in the county of Jell'erson and State ofAlabama, have invented new and useful Improvements in Self-Heating Sad-Iron's, of which the following is a specification.

This invention relates to self-heating reversible sad irons of thatclass which are provided with a burner for the Apurpose of heating oneface of the iron while the other face is in active use.

T he invention has for its object to improve the construction of theburner, and to provide a supply tank which shall beconven# ientlylocated within the handle of the burner, so as to present no obstructionand so as t0 be out of sight.

Further objcetsof the invention 'are to simplify and improve thecoiist-ruction and operation of this class of devices; and with these'and other ends in view which will readtlie invention is betterunderstood, the saine consists in the improved construction and novelarrangement and combination of parts which will be more fully describedand particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention; it being, however, understood that no limitationisnecessarily made to the recise structural details therein exhibited,liutt-hat changes, alterations and inodiiicai tions within the scope ofthe invention inay be resorted to when desired.

In the dra-wings, Figure 1 is Va vertical sectional view of a sad ironembodying the invention; Fig. 2 is an end elevation of that portion ofthe device which comprises the handle and the burner, detached. Fig. 3'is a horizontal sectional view taken on the plane indicated by the line3-3 in Fig. 1. Fig. 4 is ahorizontal sect-ional view taken on the laneindicated by the line 4-4 in Fig. 1. liigs. 5, 6 and 7 are crosssectional detail views taken on the plane indicated respectively bythelines5-5, 6-6 and 7-7 in Fig. 1. Fig. S is a vertical longitudinalSectional view illustrating a modified forni of the invention.

Corresponding parts in the several figures are denoted .by likecharacters of reference.

T he handle l of the improved sad iron is made hollow,rso as toconstitute a tank or reservoir, the saine being provided near oneeiid'with a illing aperture 2 by which 'a elosure is provided consistingof a screw plug 3.

The handle l is provided at one end with a y depending tubular arm 4carrying at its lower end the burner body B which extends laterallybeneath the handle. Inserted transversely in the tubular arm 4, adjacentto the burner body, is a screw plug 5 having an 65 aperture or passage6, the low through which is regulated by a needle valve 7 housed in theplug 5.

The burner body has in its upper portion a.

U-shaped passage 8, best seen in Fig. 3 of the 70 drawings, oneend ofwhich communicates with the passage 6, and through the latter with thetubular arm 4 and with the supply tank; the opposite end of the U-shapedpassage S receives a: nipile 9 which constitutes 75 the burner tip, andw uch is provided with an v L-shaped passage 10 discharging into thelongitudinal bore 11 of the burner body', which latter is providedthroughout the length thereof with llame oriiices 12.. body isconstructed or provided with a prim-V ing pan i3 adapted to receive.liquid fuel through an aperture 14.

The burner body is provided with an annular shoulder 15 atlording abearing for one 35 end of the body 16 of the sad iron; the opposite endof said body is pivoted upon an arm 17 connected with and depending fromthe end of the handle 1 op osite to the end having the dependingtubiilar arm 4. ordinary construction, controlled by a thumb Y piece 1Sserves to retain the body of the sad iron in position for operation, anda shield 19, to protect the hand of the operator from the heat 'issecured upon and extends be- 95 tween the arms il and 17.

From the foregoing description taken in connection with the drawingshereto annexed, the ope-ration and advantages of this invention will bereadily understood by those 100 skilled in the art to which itappertains. The construction is extremely simple and coinpact, and theseparate fuel tank, usually provided in this class of devices, is disensed with; its place being supplied by the ollow 105 handle 1 which maybe readily made of ample dimensions to contain a supply of fuelsuliicient to opera-te the device for a considerable period; at thesaine time the reservoir is very readily accessible for refilling,

time. Yarious .kinds of fuel nny be einployed in connection with theimproved Patented Septi IQQB. f g i The burner so A latch of at Aanyv110 e l i l i i 'i buiiier, but aicohol is preferredon account of itsnoli-liability to forni soot and smudge. T he fuel passes by gravitvthrough the' tubular armfl and through the. valved passage'G, where theflow is regulated by the valve 7,' to the vaporizing chamber formed bythe U- shaped passage 8. To start the burner, a. small quantity of thefuel is discharged into the bore 11 from which it passes through theaperture 14 to the priming pan 13, whiclilatter preferahlv contains apacking l0 of asbest-os or ot ier suitable porous refractory material;the latter being saturated wit fuel, the saine is ignited, and the bodyof the burner will soon be heated to a sufficient d-egrec to cause fueldischarged into. the vaporizing chamber to be convert-ed into vaporwhich, in turn, is discharged through the niple Shinto the bore 11; thefront end of the atter being open for thev admission of air which isadmitted in sufficient quantities to forni,- in connection with thevapor, a highly inflammable gas which, issuing through the orifices 1'2,is ignited; the flames impinging upon the side of the bod)v of the sadiron, wlii 'h at the time, is uppermost. One face of the iron havingbeen suliciently heated, the body of the iron is reversed, and the deiceis then ready for ope-ration; that side of the body of the iron which isuppermost be- "i g constant-ly exposed to the heating actionoff-tliieflames.

Thehjiurner is extremely simple in constructitiir and the parts of thedevice may be readily-separated, when necessary for cleansingand-,ot-`i`ier purposes, and re-assembled.

In Fig\.\S of the drawings there has been illustrated modified form ofthe burner which, under 'some circumstances, will be deemed preferable.Under this modified construction the burner is composed of a single ieeeP of cold railroad steel pipe of small t iameter, the same being bent ordoubled upon itself, and thelopen ends of the pi )e being seated in asocket Seu on which the lower end of the handle, heredbsignated H ispivoted. The upper branch or portion 41, of the pipe D contains apacking 4'2- of asbestos or other suitable material; the lower branch 43of the pi e, which extends directly beneath the upper ranch is providedwith a lurality of flame orifices 14. A drip cu 45 is arranged beneaththe lower branch o the pipe. In this form of the invention the iquidfuel contained in a tank having a discharge pipe 47 which is suitablyconnecti the. second arm,

ing provided with a duct 4S that connects the discharge pipe'.y 47 withtheuipper branch 41 of the burner pipe; the ilow o liquid from the tanktothe burner pipe being controlled bv a suitably arranged needle valve49.

ed with the support-ing block S, the latter beu Having thus fullydescribed the invention,

what is claimed as new is 1. In a sad iron, the combination of asinglcpiece struct-ure comprising a hollow horizontally-extending handleclosed at one end, a tubular de )ending arm on the opposite end of thehandle --and eomnuinicatiiig with the hollow thereof, a burner bodyextending under the handle from the bottom end of the arm, said bodyhaving a longitudinal passage provided with upwardly-dischargingopenings and having a passage communicating with the hollow arm andterminating adjacent the outer end of the longitudinal passage, and apan 'formed under the said body,

,the exterior of the body at the point adjacent the lower end of thesaid arm beine of circular exterior to form a joui-na, wit i a hollowiron journaled at one end on the said body, an arm secured to the closedend of the said handle and depending therefrom, means for connecting theiron to he lower end of and a valve controlling the flow of fuel fromthe first-mentioned arm to the vaporizing passage of theburner body. 2.A single piece casting comprising a hol-v low handle, a tubular arm onone end thereof, a burner body integrally connected with the arm andprovided w`th a return vaporizinv passage communicating with the arm anprovided with a longitudinal passage having upwardly-dischargingopenings, and a pan formed at the bott-om of the body for heating thevaporizing passage, said arm having an internally-threaded chamber, incombination with a ported plug screwed therein, a valve seat in theplug, a valve arranged to engage the seat, and a nip ple arranged on theburner body at the discharge end of the vaporizingpassage for deliveringinto the said longitudinal passage, the burner body having one portionprovided with a circular exterior to form a journal. ln testimonywhereof, I affix my signature in presence of two witnesses.
